《Deoxyfluorination of Carboxylic, Sulfonic, Phosphinic Acids and Phosphine Oxides by Perfluoroalkyl Ether Carboxylic Acids Featuring CF2O Units》 was written by Zhao, Shiyu; Guo, Yong; Su, Zhaoben; Wu, Chengying; Chen, Wei; Chen, Qing-Yun. COA of Formula: C8H15BrO2 And the article was included in Chinese Journal of Chemistry in 2021. The article conveys some information:
The synthesis of acyl fluorides RCOF [R = Br(CH2)6CH2, Ph, 1-naphthyl, etc.], sulfonyl fluorides R1SO2F [R1 = Ph, 4-MeC6H4, 4-ClC6H4, etc.] and phosphoric fluorides R2PO(F)R3 [R2 = Ph, 4-MeC6H4, 2-naphthyl, etc.; R3 = Me, F, Ph, etc.] could be realized via carbonic difluoride (COF2) generated in situ from thermal degradation of the PFECA salt. The use of potassium salts of perfluoroalkyl ether carboxylic acids (PFECA) was reported featuring CF2O units as deoxyfluorination reagents, which were generated mainly as byproducts in the manufacture of hexafluoropropene oxide (HFPO). After reading the article, we found that the author used 8-Bromooctanoic acid(cas: 17696-11-6COA of Formula: C8H15BrO2)
8-Bromooctanoic acid(cas: 17696-11-6) acid is used in the synthesis of 8-(N-Methyl-4,4′-bipyridinyl)- octanoic acid. 8-Mercaptooctanoic acid was prepared from 8-bromooctanoic acid. And 8-Bromooctanoic Acid is a useful compound for sonodynamic therapy.COA of Formula: C8H15BrO2
